• Description: Stacker Delivery Sensor Delay Jam : Jam in the top left door. Upper-paper-path-entry sensor (PI103) has signaled that paper has passed but upper paper-path-exit sensor PI104 does not actuate within the expected time, suggesting that the paper has jammed between PI103 and PI104 in the upper paper path. The specific jam error code will be one of the following forms: • 13.64.D1 • 13.64.D2 • 13.64.D3
• Remedy: 1. Remove any media jammed in the upper paper path between sensor PI103 and sensor PI104. 2. Check the paper path between sensor PI103 and sensor PI104 for obstructions that may be preventing the media from reaching PI104. 3. Verify that the PI104 sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. 4. Make sure that sensor PI104 is securely fastened to the chassis and wiring is properly connected to sensor.

• Remedy: 1. Remove any media in the upper paper path that might be activating sensor SR101. 2. Print and analyze the event log, looking for Printer- or MFP-related jams occurring either in the fuser or in the duplexer. These errors might be the result of media failing to reach the output device in the correct amount of time. Troubleshoot all Printer Engine Jams first. 3. Make sure that media is in good condition, and not wrinkled or damaged. 4. Make sure that the correct paper size in the trays is selected according the paper size being fed. 5. Verify that the finisher is securely fastened to the engine. 6. Make sure that the finisher and Printer are correctly aligned. 7. Adjust the finisher castors to obtain a uniform gap between the finisher and the engine. 8. With the engine-to-finisher gap correct, make sure that the finisher paper path entry point is aligned with the Printer exit point. 9. Check the finisher entry-point guides for damage. 10. Carefully clean the sensor body, by gently blowing clean air across the sensor to remove dust and debris. 11. Verify that the sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. 12. Perform Sensor test on SR101. If not functioning or damaged replace the Sensor. 13. Check wiring from sensor SR101 to the Reverse Driver PCA connector for damage. 14. Only if the error persists and none of the previous steps correct the problem, replace the Reverse Driver PCA.
